Any good iMac accessories?

hello,
Does anyone have any suggestions for iMac accessories? I am a youtuber and plan to post a review of it on my channel. Any suggestions are welcome.
P.S. I'm not looking for speakers, monitor, mice, or keyboards

A good USB or bluetooth mouse is never a bad idea. I personally think that the Mighty Mouse is over priced and not as good as most people claim. I would look into the logitech mx revolution if you want the best USB mouse out there or, microsoft also makes a nice bluetooth mouse whose colors go nicely with Apple products.
